Appearance of Uchiha Obito
As a child, Obito had short, spiky, black hair and black eyes. He wore a long sleeved blue uniform with metal plating on the part that reached the back of his hands, as well as a blue jacket with an orange collar and trimmings. The jacket was fastened to the rest of the outfit by two buttons on the collar, and has the Uchiha clan crest at the back. He also wore a white belt, shinobi sandals, the standard Konoha dark blue forehead protector, and a pair of goggles with orange lens connected to ear protectors. After he was retrieved from Kusagakure, Madara replaced his destroyed right side with artificial substance from Hashirama's living clone. The right side of his face still remains heavily scarred in a manner similar to deeply-aged wrinkles. During his rehabilitation, Obito grew his hair out, with the shape similar to that of Madara's. He eventually cut it back down to the short length as in his childhood. During the Nine-Tails' attack he wore a long hooded black cloak and a yellow-orange mask with a pattern that resembled his facial scar, some time before the Nine-Tails' attack on Konoha. During his meetings with Kisame, and Itachi respectively, Obito was seen with long hair yet again, but he later cut it back to its usual length which he wears to this day, he also wore Uchiha robes with a sash on his waist and a yellow-orange mask that had a black flame pattern, that resembled Amaterasu's flame. During his meeting with Kisame, he wore a dark blue kimono and with most of limbs, including his entire chest and stomach heavily wrapped in gauze; the only exceptions are his lack of gauze on his right arm and hand.
As an adult, under the name "Tobi", Obito created an orange mask with spiral-pattern that only shows his right eye, a reminiscence of when Spiral Zetsu encased him. Under his Akatsuki cloak, he wears a black long-sleeve top that also covers his neck and chin, a pair of black gloves, and a pair of dark-coloured pants along with the standard Akatsuki shoes and white stirrups. On his waist, he wears a thick black belt with armour-like metal plates attached to it. He wore the same metal plates on his shoulders with a green scarf before becoming Deidara's partner. He wore blue nail polish on his fingers and toes (black in the manga). As Tobi, he wore dark grey (black in the manga) gloves and Sasori's ring on his left thumb.
After he acquired the Rinnegan, Obito started wearing a new mask made of strong materials suited for the looming Fourth Shinobi World War. The mask was white with a purple tint that covers the entire upper-half of Obito's head with a design that resembled the Ten-Tails' eye, consisting of a ripple-pattern with three tomoe around the centre; two of these tomoe acted as the mask's eye-holes. He noted to Naruto that this new mask had been specifically designed for combat, making it very durable. He also dons the Uchiha clan's traditional clothing during the Warring States Period. This attire includes a pair of black pants and gloves, with a white, presumed form-fitting shirt (black in the anime prior to episode 325) underneath. Over this he wears a purple, high-collared, long sleeve mantle that splits down the lower half and has the Uchiha crest on the back. Around his waist he wears a simple, light-purple obi and a belt. Strapped to his back, he carried a purple gunbai with black trimmings and black tomoe, connected to a black chain that ran up his right sleeve. During his first meeting with Madara Uchiha during the Ten-Tails Revival Arc, he removed the chain attached to the gunbai and handed the fan back to Madara.
After being forced to use the Outer Path: Samsara of Heavenly Life Technique, Obito's hair turned white and the right half of his body turned completely black due to the influence of Madara's will, his appearance resembling Zetsu. Immediately after becoming the Ten-Tails' jinchūriki, Obito's body undergoes a drastic transformation. He still possesses white hair, his skin turns white; and his Sharingan and Rinnegan in addition to ten protrusions coming from his back, five near his shoulder and five near his hips, as well as a black assortment of ten magatama on his back; one large one, with a black Rinnegan-like pattern within it, on his mid-back, and nine smaller ones, arranged in rows of three, below it. In addition, the entire right half of his body has acquired a unique black, scale-like pattern across it, replacing the scars he acquired as a child, including repairing all the wounds inflicted on him during the Fourth Shinobi World War. When Obito managed to regain control of the Ten-Tails, he undergoes yet another transformation. In this new form, the ten protrusions on his back now form the collar and coattails of a haori. Two horns also sprout from his forehead; the left smaller than the right. Additionally, he gains six magatama markings across his chest.
